Exhibit (a)(7) MFS Government Markets Income Trust Commences Tender Offer Contact: John Reilly 617-954-5305 For Immediate Release BOSTON (October 17, 2007) - MFS Government Markets Income Trust (NYSE: MGF) today commenced a cash tender offer for the Trust's common stock. The Trust is offering to purchase up to 19,249,709 shares of the outstanding common stock at a price per share equal to 99% of the net asset value per share (NAV) as of market close on the expiration date of the offer. The offer expires at midnight on November 14, 2007, unless extended. The offer is also subject to a number of conditions, including shareholder approval at the Trust's November 1 annual meeting of a proposal that would allow the Trust to borrow money for leveraging purposes. Over the past six months, the Trustees have taken a number of actions to address the Trust's share price discount to NAV, including changing the Trust's investment strategy to seek a higher yield from the portion of the portfolio not required to be invested in U.S. government or agency securities, approving a proposal to seek shareholder approval to allow the Trust to use leverage, and approving a level-distribution plan that took effect September 1, 2007. The Trustees believe that the tender offer will provide shareholders the opportunity to sell their shares at a price close to NAV, while permitting other shareholders who do not wish to sell to continue to have the benefits of the closed-end structure. The discount to NAV at which the tender offer is being made is expected to offset the costs associated with conducting the tender offer. MFS manages $202 billion in assets on behalf of more than 5 million individual and institutional investors worldwide as of June 30, 2007. The company traces its origins to 1924 and the creation of America's first mutual fund.
